6002 Eetion, provisional designation: , is a mid-sized Jupiter trojan from the Trojan camp, approximately in diameter. It was discovered by Poul Jensen at the Brorfelde Observatory in 1988, and has not been named since its numbering in June 1994. The dark Jovian asteroid has a rotation period of 12.9 hours. In 2021, it was named from Greek mythology after King Eetion, who was killed by Achilles during the raid on Thebe. Discovery Eetion discovered on 8 September 1988, by Danish astronomer Poul Jensen at the Brorfelde Observatory near Holbæk, Denmark, who on very same night also discovered the Jupiter trojan , and several other main-belt asteroids including , , , , and . Orbit and classification Eetion is a dark Jovian asteroid in a 1:1 orbital resonance with Jupiter. It is located in the trailering Trojan camp at the Gas Giant's Lagrangian point, 60° behind its orbit . It is also a non-family asteroid of the Jovian background population. It orbits the Sun at a distance of 4.7–5.7 AU once every 11 years and 11 months (4,361 days; semi-major axis of 5.22 AU). Its orbit has an eccentricity of 0.09 and an inclination of 16° with respect to the ecliptic. A first precovery was taken at Palomar Observatory in September 1953, extending the body's observation arc by 35 years prior to its official discovery observation at Brorfelde. Numbering and naming This minor planet was numbered by the Minor Planet Center on 23 June 1994 (). On 29 November 2021, IAU's Working Group Small Body Nomenclature it from Greek mythology after King Eetion of Thebe Hypoplakia, father of Andromache, and father-in-law of Hector. Eetion was killed during the raid on Thebe by Achilles. Physical characteristics This Jupiter trojan is an assumed, carbonaceous C-type asteroid. Rotation period In February 1993, Eetion was observed by astronomers Stefano Mottola and Mario Di Martino with the ESO 1-metre telescope and its DLR MkII CCD-camera at La Silla in Chile. The photometric observations were used to build a lightcurve showing a rotation period of hours with a brightness variation of magnitude (). It was the body's first determined rotation period in literature. Diameter and albedo According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Eetion measures 40.4 kilometers in diameter and its surface has an albedo of 0.075, while the Collaborative Asteroid Lightcurve Link assumes a standard
